Incident analysis

Meinhardt Group was listed by Crypto24 ransomware, a group with 47 victims recorded in this database. The listing appeared on the group's leak site on October 27, 2025.

Meinhardt Group is based in Singapore and operates in the Construction sector. Singapore ranks #16 worldwide for ransomware disclosures, with 192 victims in this database.

Sector context. Construction firms often hold sensitive project data, client financials, and intellectual property. The industry's typically lean IT security teams can make them more vulnerable.

Crypto24 typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
